Higher-order kinematic analyses of a planar parallel robot based on screw theory
(2020)
This paper presents the higher-order kinematic analyses of a planar parallel robot, addressed by means of the theory of screws. The reduced velocity, acceleration, jerk and hyper-jerk state for the end-effector of robot ...
Trajectory-tracking control of a planar parallel robot using generalized predictive control with constraints
(2020)
This paper presents the generalized predictive control with constraints, implemented to a planar parallel robot in order to calculate and track the desired trajectory of the end-effector of this robot. The manipulator is ...
